Error: invalid wire type 4 at offset 2332

Description

I tried to run syft.js together with a hosted FL plan for MNIST that I created and hosted with the notebooks from the PySyft repo (/examples/experimental/FL Training Plan). I followed the instructions in the syft.js repo and opened the with-grid example. However when starting the worker, there seem to be a number of issues:

1. The upload speed test takes extremely long and blocks the whole machine. I had to manually kill my chrome process to exit the syft.js tab. This is weird because the 64MB buffer you created should not take too long to send to a localhost server. I solved this by just returning Promise.resolve(1000) in the getUploadSpeed function.
2. Next, unserializing the plan protobuf that is returned by the server fails with the following error:

Error: invalid wire type 4 at offset 2332

The unserialization of the model protobuf that is executed right before that works.

How to Reproduce

1. Setup PyGrid and PySyft
2. Create and host a plan the PySyft notebook example
3. Setup syft.js
4. Click "Start FL Worker"

We will look into this @erksch, sorry for the delay. @vvmnnnkv have you come across this?

I've separated upload speed test problem in #150
@erksch could you put more details there?
Thanks!
